Patent Type: Invention Disclosure

Application (Patent) No.: CN201711438939.6

The present invention relates to a composite material needle and thread integrated sewing needle, which relates to the field of sewing needles for composite material preforms. The integrated sewing needle is composed of suture thread (fiber bundle) and sewing needle (composite material thin rod formed by combining fiber bundle and resin) in the length direction, and the fiber reinforcement in the suture thread and sewing needle is the same fiber assembly. The diameter of the sewing needle is between 0.1mm and 5mm, and the length is between 10mm and 150mm. The length of the suture is between 50mm and 1.5m. The volume content of fibers in sewing needles is between 20% and 80%. The sewing needle of the present invention does not require the work of threading the needle hole during use, which can greatly improve work efficiency. Moreover, due to the natural connection of fiber aggregates at the junction of the sewing needle and the suture thread, there will be no easy breakage point that exists due to the 360 degree folding of the suture thread at the junction of the traditional steel needle and the suture thread.
